Evaluation of chlorogenic acid accumulation in cultivated and wild apples

• Chlorogenic acid content was measured in mature fruits of 379 apple accessions. • CGA content has undergone selection during apple domestication. • MdPAL3 and MdHQT are key genes controlling chlorogenic acid accumulation in apple fruits. Although chlorogenic acid (CGA) is a polyphenol compound with dietary benefits, the mechanism underlying its accumulation in apple fruits remains elusive. In this study, CGA content was measured in mature...
